Chinese-led team achieves 10,000 km Quantum-Secured Communication for the first time in the world.
An international research team, led by Chinese scientists, has successfully achieved quantum-secured communication over a distance of more than 12,900 kilometers between China and South Africa.
Utilizing the Jinan-1 micro-nano satellite along with compact ground stations, this breakthrough highlights the potential for secure quantum communication on a global level.
For the first time internationally, researchers from the University of Science and Technology of China established real-time quantum key distribution (QKD) between the satellite and miniaturized ground stations, including one based in Stellenbosch, South Africa.
Building on this engineering success, Chinese scientists, in collaboration with Stellenbosch University, have demonstrated the longest recorded hacker-proof communication across hemispheres.
The findings were published in the journal Nature on Wednesday. A peer reviewer from the journal praised the research as a “technically impressive achievement,” emphasizing its significance in advancing satellite QKD technology and paving the way for large-scale, secure communication networks.
